This class wraps the next_dev() function for iterating through the | ||

watching volumes. | ||

\brief Fills out the passed in BVolume object with the boot volume. | ||

Currently, this method looks for the volume that is mounted at "/boot". | ||
The only way to fool the system into thinking that there is not a boot | ||
volume is to rename "/boot" -- but, please refrain from doing this. | ||

refer to the boot volume. | ||

otherwise. | ||

\fn status_t BVolumeRoster::StartWatching(BMessenger messenger) | ||
\brief Starts watching the available volumes for changes. | ||
|
||
Notifications are sent to the specified target whenever a volume is | ||
mounted or unmounted. The format of the notification messages is | ||
described under watch_node(). Actually BVolumeRoster just provides a | ||
more convenient interface for it. | ||
|
||
If StartWatching() has been called before with another target and no | ||
StopWatching() since, StopWatching() is called first, so that the former | ||
target won't receive any notifications anymore. | ||
|
||
When the object is destroyed all watching ends as well. | ||
|
||
\param messenger The target which the notification messages are sent. | ||
|
||
\return A status code. | ||
\retval B_OK Everything went fine. | ||
\retval B_BAD_VALUE The supplied BMessenger was invalid. | ||
\retval B_NO_MEMORY There was insufficient memory to carry out this | ||
operation. | ||
